Mechanical properties of Sn-0.7Cu/Si 3N 4 lead-free composite solder
(Elsevier B.V., 2012-10)
The use of reinforcing high performance ceramic particulates in monolithic lead-free solder is one way to improve the service temperature and mechanical behavior of a solder joint. In this study, various compositions of ...
Fly ash-based geopolymer lightweight concrete using foaming agent
(MDPI, Basel, Switzerland., 2012-06)
In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium ...
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)
The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ...
Reviews on the Geopolymer materials for coating application
(Scientific.Net, 2012-12)
The application of geopolymer has been expand in many areas where before this it only used for the production of cement and concrete. One of the new applications of geopolymer is for coating. Metakaolin, fly ash and ...

Influence of the user's hand on mutual coupling of dual-antenna structures on mobile terminal
(Institute of Electrical and Electronics Engineers (IEEE), 2012-03-26)
This paper studies the influence of the user's hand on the mutual coupling of dual-antenna structures on a mobile terminal. The terminal consists of two planar inverted-F antennas (PIFA) on a typical 100 × 40 mm 2 mobile ...
Correlation between Na 2SiO 3/NaOH ratio and fly ash/alkaline activator ratio to the strength of geopolymer
(Trans Tech Publications, 2012)
Geopolymer requires an alkaline activator to induce it pozzolanic property and to accelerate the geopolymerisation process. The geopolymerisation process occurs due to the mixing of fly ash, sodium silicate and sodium ...
